Control of garlic fly maggots with 48% Lesbon

Yuan Yong from Group 2 of Jixing Village, Tongshang Town, Dafeng City, Jiangsu Province wrote that the local garlic field occurred in 2005. When a plant of garlic was dug up, you could see 6 flies and 8 maggots in the rhizome, resulting in almost no harvest in some fields. Many garlic farmers were anxious. I hope we can ask experts to give us a solution.

For this problem, we consulted the relevant experts of the Plant Protection Station of the Department of Agriculture and Forestry of Jiangsu Province. Experts say onion flies, also known as onion maggots and garlic maggots, belong to the family Muscidae of Diptera and are common pests on green onions. In light cases, the output will be reduced by 10% to 20%, the heavy ones will reach more than 30%, and even the seeds will be destroyed. In addition to harming onions, it can also harm garlic, leeks and other lily vegetables. The larvae eat into the bulbs such as onions and garlic, causing decay, causing the upper leaves to wither and wilt to death. Control method: it can be poured with 48% Lexben (chlorpyrifos) 800 times liquid, with 500 kg per mu.
